ANTISLIPPING- SANDAL.

7 Application filed July 9,

To all whom it may concern l Be it known that BERT NOBLET'II'L, a citizen of the United States of America, residing at \Vinchester, in the county of Clark and State of Kentucky, has invented new and useful Improvements in Antislipping Sandals, of which the fOllOWiIig is a specification.

The object of the invention is to provide a simple and efficient means for emergency application to shoes and boots des gned for personal wear as a means of insuring a safe foot hold in snow and on ice and adapted to be applied without special preparation of the shoe and without involving any injury to the latter; and in that connection to provide a device which is of comparatively light and readily foldable construction adapting it to .be readily carried in, the pocket or any like portable receptacle for use when required; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawii'igs, wherein:

Figure l is a side view of a device embodying the invent-ion applied in the operative position to a shoe.

Figure 2 is a plan view of the same.

Figure 3 is an inverted plan View thereof.

Figure 4 is a detail view of the special ice creeper attachment adapted for use when required and optionally applicable to the sandal.

Figure 5 is a detail perspective view illustrating the kind of chain which forms the tread strands of the device.

The device consists essentially of a tread 1.0 formed of a net work of relatively widely spaced intersecting longitudinal and transverse chains 11 and 12 provided with a marginal strand 13 adapted to follow the outline of the toe portion of the shoe upper above the plane of the sole and having the adjacent extremities of the strands forming the tread attached thereto, said marginal strands hav' ing an elastic contractile insert 14 in the form of a heel embracing loop which in the construction illustrated is represented by a rubber band terminally attached to eyes 15 at the rear ends of the marginal strand and serving to exert a rearward strain upon the latter to hold it with the attached tread members or strands in proper position with relation to the toe portion of the shoe to which it is applied.

The tread strands are preferably con Specification of Letters Patent.

structed of chains as above indicated, having the two-way links shown in the drawing, said two-way links beingof the form in which the terminal eyes 16 thereof are disposed in perpendicular planes so that in use the tread strands are adapted to roll or shift by a rolling action to afford a grip upon a slippery surface and filling inequalities in such surface rather than to cut thereinto after the manner of spikes or similar antislipping devices which have heretofore been devised. The relative freedom of movement of the tread strands or elements is indicated because of the fact that the resulting tendency to cut or chafe or otherwise injure the surface of the sole of the shoe is minimized. The marginal strand is preferably constructed of flat round links which lie in a relatively flat condition against the shoe upper or vamp and the marginal strand is adapted to be drawn taut by the contractile band or insert so as to be retained against sliding or shiftmg movement and hence chafing the shoe upper.

The side portions of the marginal strand are transversely connected above the shoe by elastic, contractile retainers 17' of rubber or like material which bear upon the surface of the upper at the toe portion of the shoe and may be terminally split as shown to provide laterally divergent or radiating arms for connection with the marginal strand atspaced points to guard against lateral displacement of the tread and yet adapt the device to the movements of the foot of the wearer to an extent suflicient to avoid discomfort.

In traversing surfaces of a particularly hard and slippery character such as ice it is preferable to supplement the frictional action of the tread mesh by employing one or more tread rollers or balls 18, which may be attached when required or may be dispensed with under ordinary conditions. This ball is provided with radial blades or edges 19 and is rotatably mounted upon a spindle link 20 having terminally attached chain elements for engagement with the strands of the tread. The ball is thus loosely held in one of the open spaces or meshes of the tread for rolling movement and cutting action to atford a grip upon a hard and slippery surface such as ice or the equivalent thereof.

Having described the invention, what is claimed as new and useful is 1. An anti-skid sandal having a tread of ture.

3. An anti-skid sandal having a tread of strands arranged in mesh form and means for securing the same in operative relation with the tread portion of a shoe in combination with a supplemental tread element c0nsisting of a link pin having means for attachment to strands of said tread and a radially edged ball revolubly mounted upon said in. i In testimony wherof he affixes his signa- BERT NOBLETTE.
